Propagation of Vangueriopsis coriacea Robyns
Vangueriopsis coriacea Robyns, commonly known as the "Forest Pears", is a beautiful plant that belongs to the Rubiaceae family. The plant is native to Cameroon, West Africa, and is known for its ornamental and medicinal value. Propagation of Vangueriopsis coriacea can be done through the following methods:
Seed Propagation
Seed propagation is one of the most common methods of propagation for Vangueriopsis coriacea. The seeds should be collected from the ripen fruit and dried under the sun to loosen the husk. The husk should be removed and the seed should be soaked in warm water overnight before planting. The seed should be planted in a well-draining soil mix and kept moist. Germination is expected to occur within two to three weeks. The seedlings can be transplanted to a larger container once they grow their second pair of leaves.
Stem Cutting Propagation
Vangueriopsis coriacea can also be propagated through stem cuttings. Softwood cuttings should be taken in the rainy season when the plant is actively growing. The stem cuttings should be 6-10 cm long and contain a few leaves. They should be dipped in rooting hormone and inserted into a well-draining soil mix. The cuttings should be kept in a humid environment until they develop roots. They can be transplanted to a larger container once they develop a strong root system.
Air Layering Propagation
Air layering is another propagation method that can be used for Vangueriopsis coriacea. The stem can be selected at least 15 cm from the topmost part of the plant. A notch should be made in the stem and covered with soil or moss to keep it moist. A plastic bag can be wrapped around the moss or soil to create a humid environment. Roots are expected to develop within a few weeks, and the propagated plant can be cut off and planted in a well-draining soil mix.
Propagation of Vangueriopsis coriacea should be done with caution to ensure the success of the propagation. The plant requires optimal growing conditions, such as adequate light, humidity, and nutrients to thrive.
